The Perfluorinated sulfonic acid ion exchange membranes for fuel cell, is also called proton exchange membranes, are produced with the new casting method, the casting process can be combined with doping technology,for the hydrogen fuel cell, we add EPTFE(expanded polytetrafluoroethylene) microporous reinforcing material to the traditional proton exchange membrane, which has the characteristics of high strength, high conductivity, and low ion permeability, and so on.
The fuel cell is a type of power generation device. The working principle of a fuel cell is that the battery contains two electrodes, cathode and anode, which are filled with electrolyte, and the two electrodes are formed by a permeable ion exchange membrane. Hydrogen enters the anode (negative electrode) of the fuel cell, and oxygen enters the fuel cell from the cathode. Through the action of the catalyst, the hydrogen molecules of the anode are decomposed into two protons and two electrons. The protons are 'attracted' by the oxygen to the other side of the ion exchange membrane. Under the action of the catalyst, protons, oxygen, and electrons react to form water molecules, so water can be said to be the only emissions from fuel cells. Since the oxygen supplied to the cathode plate can be obtained from the air, as long as the anode is continuously supplied with hydrogen, the cathode is supplied with oxygen, and the water is taken away in time, the electrical energy can be continuously provided. The "hydrogen" fuel used in fuel cells can come from the hydrogen produced by the electrolysis of water and any hydrocarbons, such as natural gas, methanol, ethanol (alcohol), biogas, and so on. Fuel cells generate electricity and water through a chemical reaction using hydrogen and oxygen. Not only is it completely pollution-free, but it also avoids the time-consuming problem of traditional battery charging. It is currently the most promising new energy method.
